The two mods I plan on making is changing the wheels and removing the orange reflectors on the headlights. Not sure if I can remove them from the existing headlights, or, will need to order a new set from the aftermarket/global Kia parts bin.

Someone spotted one on the road being tested and it's made me start seriously considering the yellow. I'm assuming that'll be the lowest volume color? He spoke to the driver briefly who said it was "very fun in Sport mode"

The most Test-Stingers you can see on YouTube in Asia are Red (some black but no other color).
The same Red as shown on NAIAS, GIMS,...
Why should the other colors looks different then there?
I think it would be the same...
